From his view in retirement, David Comer spoke with us about continuing to learn, staying engaged in an engineering career, and how the Galileo memory module worked.

Brittany Postnikoff (@Straithe) spoke with us about scary robots, neat stickers, and contributing to open source projects.

Brittany’s website is straithe.com and her sticker channel is twitch.tv/str41the. Her github repo has curated reading lists on technical topics.

She’s working at Great Scott Gadgets, maker of a variety of hardware tools including Luna, a toolkit for working with USB. (This was mentioned on a previous Embedded show, 337: Not Completely Explode with Kate Tempkin.)

And if you want Embedded merchandise like mugs, mousepads, and wall art, we have a store for you.

Tenaya Hurst Conklin (@TenayaHurst) discussed STEAM teaching tools and kits from RAFT (@RAFTBayArea). 

RAFT is at raft.net. The Abiotic Dissection activity is pretty amusing (from the STEAM Learning Sheets) as are the games in the idea sheets. They also have a summer camp and a Youtube channel.

Tenaya’s website is roguemaking.com. She was previously on Embedded 49: Is that an Arduino in your pocket?

Sarah Petkus offers to let her robot lick Christopher's leg. Christopher agrees reluctantly once we determine the saliva will be anti-bacterial hand sanitizer.

Sarah is a kinetic artist and some of her projects include a robot army (built your own from parts printed out or purchased at robot-army.com), Noodlefeet, and Carl (the flamingo of pendulum inversion). Her Zoness.com site is an umbrella for her drawn and robotic art. Specifically, you may enjoy her webcomic Gravity Road, her YouTube channel, and/or her Robotic Arts blog.

Some other topics we discussed:

• Sarah got into mechatronics at her time as SAIC.

• Festo's air jellyfish on youtube

• Algodoo.com 2d physics simulator

• Woodgears.ca for 3d printable gears

It’s another Elecia and Chris episode and this time we cover handling hourly work when the task doesn’t neatly divide into hours, using Docker (and Conda and Virtualenv) for development, growing the podcast, overdoing conference talks, and trying to find a new laptop. Phew!

The Embedded Online Conference is coming up the week of May 17th 2021, and Elecia’s talk will be Buried Treasure and Map Files (Note: the coupon code is still valid and mentioned early in the episode. Elecia will also put up a copy of her talk on YouTube after some time.)

Anne Barela (@anne_engineer) spoke with us about working as an engineer in the US Foreign Service and writing tutorials for Adafruit. Anne has also written two books: Getting Started with Adafruit Trinket and Getting Started with Adafruit Circuit Playground Express.

To see Anne’s writing on Adafruit, check out her page: learn.adafruit.com/users/AnneBarela

We also looked at Adafruit’s Home Automation board.

Doug Ellison (@doug_ellison), Engineering Camera Team Lead at NASA’s JPL and Martian photographer, spoke with us about low power systems, cameras, clouds, and dust devils on Mars.

The best paper for learning more is from NASA’s JPL site: The Mars Science Laboratory Engineering Cameras

Alvaro Prieto (@alvaroprieto) spoke with us about cheese, making, work, the reverse engineering podcast, weather, and motivation.

Alvaro is a host of the Unnamed Reverse Engineering podcast. Some of his favorite episodes include #41 with Samy Kamkar, #14 with Joe Grand, and #23 with Major Malfunction. (Jen Costillo co-hosts the show and has been on Embedded several times.)

Alvaro works at Sofar Ocean, making oceanic sensing platforms. He has a personal website linking to his other exploits.

We talked about some Embedded episodes as well:

• #282 with Laughlin Barker about OpenROV

• #174 with Evan Shapiro about baby monitors and professional poker 

Also, we’ve all really enjoyed the Disney’s Mandolorian.

Chris and Elecia talk with each other about contracting, architecture, origami research, Digilent’s new oscilloscope, TensorFlow, map files, conference talks, art and the upcoming 12AX7 album.

Digilent sent us a pre-production Analog Discovery Pro ADP3450.

Elecia’s Origami Github.

12XA7, we’ll let you know when the Kickstarter goes live.

Finally! An episode with version control! And D&D! Chris Svec (@christophersvec) joins us to discuss why version control is critical to professional software development and what the most important concepts are.

T-Shirts are on sale for a limited time: US distributor and EU distributor.

You can read more from Chris on the Embedded Blog. He writes the ESE101 column (new posts soon!).

If you are new to version control or learning git, Atlassian has a great set of posts and tutorials from high level “what is version control?” to helping you figure out good usage models (Svec mentioned gitflow). Atlassian has an interactive tutorial that lets you try out the repository commands (or try the Github interactive tutorials). Of course, there is a good O’Reilly book about git.

If you are using SVN (aka Subversion), the Red Bean book from O’Reilly is a good resource.
